Dennis Purinton began as a general contractor in 1979 in Granby Connecticut.  In March of 1984 Dennis formed Purinton Builders, Inc., specializing in cast-    in-place concrete foundations; within two years Dennis added complete site work services.  In 1999/2000 he made the transition from wood forms to Western Forms aluminum forms allowing for a higher quality smooth wall with curves and angles.  Dennis further expanded in 2003 to include foundation waterproofing.  He poured his first of many insulated foundations in 2004     and now is a certified installer and the northeast distributor for THERMOMASS Insulation Systems.  Dennis also began working on environmentally friendly green concrete mix designs utilizing replacement cements and fly ash.  Dennis was honored to receive Contractor of the Year in 2007 from the National Concrete Foundation Association.
